Title: Heat-insulating pipe for oil explotation
IPC: E21B17/04
Filed: 1969-02-19
Abstract: Pipe for feeding a hot medium into an oil containing layer for ensuring normal working and reduction of heat losses has two walls separated by a heat insulating material. To allow for expansion at the connecting of the inner pipes when a hot medium is passed through, an inner pipe is welded by means of a disc to the corresponding outer pipe, whilst the end of the other inner pipe can slide along the inner wall of the other inner pipe with which it is loosely connected. A metal sleeve, which is only welded on to the inner wall of the outer pipe serves to hold the heat insulating material, and a second sleeve which is only screwed in the outer pipe serves to fix heat insulating material in that pipe during assembly and fitting in the drill hole of the conveying system. The heat insulating material is fitted in the circular space between the coupling joint of the outer pipes and the wall of the inner pipe.

Title: Continuous production of resin-bonded mineral fibre - panels
IPC: B28B1/52
Filed: 1969-10-20
Abstract: Mineral fibre panels, in which the fibres are mainly oriented perpendicular to the surfaces of the panel, are produced continuously by (a) distributing the mineral fibres over a conveyor belt to form a fibrous mat, (b) spraying the fibres with a liquid, thermosetting binder, (c) folding the fibrous mat along fold lines perpendicular to the lengthwise direction of the fibrous mat, (d) compressing the parts of the fibrous mat between the fold lines with the flat sides directed towards each other and (e) curing the binder sprayed onto the fibres. The process provides mineral fibre panels with improved properties, especially an increased capacity for withdrawing loads with the provision of a special surface layer. The panels obtained have a smooth surface. The process produces the panels at a high rate on a continuous basis.

Title: Oar or canoe paddle with improved form of blade
IPC: B63H16/04
Filed: 1991-06-06
Abstract: At the beginning of the stroke, a blade of an oar or canoe paddle supplies propulsive force via the hydrodynamic lift principle. After the flow around the blade has been released, the propulsive force is supplied via the resistance principle. The propulsive efficiency is higher in the "hydrodynamic lift" section than in the "resistance" section of the stroke. The object of the invention, by using a thickened and rounded tip, optionally in combination with one or more gaps, is to delay the moment at which the flow around the blade is released, thus improving the overall propulsive efficiency. <IMAGE>
